Two unrelated stabbings in San Diego

In the first incident, a 15-year-old boy was approached by two male juveniles about 8:50 p.m. on Polk Avenue at Winona Avenue in City Heights. They gave him a gang challenge. The boy said that he was not in a gang. The two chased him, and one stabbed the boy in the back, San Diego police Officer David Stafford said.

The second incident was reported about 10:30 p.m. in the East Village. A 55-year-old transient was approached by a 37-year-old man on Imperial Avenue at 15th Street. The man called the transient a name and stabbed him on the forearm. Officers who were nearby took the assailant into custody on suspicion of assault with a deadly weapon.

Both victims were taken to a hospital. Neither of the wounds were life-threatening, Stafford said.
